    摘要: Disclosed is a pixel for improving an image quality. A pixel includes: an organic light emitting diode; a first transistor to control a current supplied to the organic light emitting diode from a first power source connected to a first electrode of the first transistor in response to a voltage applied to a first node; a second transistor connected between the first node and a second node, and turned on when a scan signal is supplied to a scan line; a first capacitor connected between the second node and a data line; and a third transistor connected between a second electrode of the first transistor and the second node, and turned on when a common control signal is supplied to a common control line.

    摘要: A touch screen display is disclosed. In one aspect, the touch screen display includes a plurality of first touch electrodes each including first and second ends opposing each other and a plurality of second touch electrodes crossing the first touch electrodes. The touch screen display also includes a first voltage line providing a voltage, a first signal line providing a touch driving signal, and a plurality of first switching units respectively connected to the first touch electrodes. Each of the first switching units is electrically connected to the first voltage line, the first signal line, and the first end of a corresponding first touch electrode. Each of the first switching units alternately provides one of the voltage and the touch driving signal to the corresponding first touch electrode.

    摘要: An organic light emitting diode includes a hole injection layer, a hole transport layer, an optical compensation layer, an emission layer, an electron transport layer and an electron injection layer. The optical compensation layer is disposed on the hole transport layer and includes a phosphorescent host material. Thus, an electron barrier on an interface between the optical compensation layer and an emission layer may be reduced. Thus, the luminance efficiency in a low gray scale area may be decreased, and the stain and roll-off phenomenon in the low gray scale area may be improved.
